2 Claims.

This invention relates to dog racing devices particularly to certain improvements upon the dog racing structures illustrated, described and claimed in Patent 1,733,069 of October 22, 1929 and 1,703,496 granted February 26, 1929.

An object of this invention is to provide improved means whereby current is transmitted to the motor of the carriage.

. Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing, wherein:-

Figure 1 is a plan View of a portion of the race track constructed in accordance with my invention;

Figure 2 is an end elevation of the same, the track being shown in section;

Fig. 3 is a detail plan view of the contact brush, the pin holding the contact brush in place being in section.

Referring to this drawing, it will be seen that the track structure for the race course includes upright posts 10 which are approximately two feet high instead of being approximately seven feet high as in ordinary installations and which are provided with the outstanding supports 11 having the depending rail 12 and the horizontal rail 13 which is attached to the depending rail in any suitable manner and is preferably of wood or any suitable material. The rails 12 and 13 are formed of sections, the rail sections 12 being tongued and grooved at their ends and the rails 13 having their upper and lower faces at opposite ends alternately rabbetted to receive the rabbetted ends of the adjacent rail sections.

Operating on the track is a carriage comprising a motor supporting frame 15, substantially of the construction shown in Patent No. 1,703, i96 above referred to. The axle of the motor 20 carries upon it the wheels 21 which bear against the under face of the track 13 and are urged against the under face of the track by springs 18. Mounted upon the upper ends of the members 16 and 17 are L-shaped supports 22 which carry wheels 23 bearing against the upper face of the track 13 and supporting the motor. It will be seen that the springs 18 urge the wheels 21 upward into good tractive engagement with the under face of the track 18. Also mounted upon the members 22 are the forward and rear pairs of inwardly extending arms 24 which carry upon them the guide wheels 25 which bear against the lateral faces of the vertical portion 12 of the 5 track. These arms 24 are shown as pivoted tothe members 22 and these arms may be yieldingly urged against the lateral faces of the portion 12, to thus guide the carriage and prevent it from slipping off the track in any way.

For the purpose of carrying electric current to the motor, I pivotally mount upon the rearwardly extending members 26 the brushes 27 which as illustrated in Fig. 3 are curved metal plates which extend rearward and inward and bear against conductive elements 28 on the side faces of the track. These brushes 27 are urged inward by means of springs 29 bearing at their outer ends against extension arms 30 on the members 26. Conductors 31 lead from these brushes to the motor. It will be seen that the pivotal support for the brushes and the springs 29 provide for any side swaying of the carriage and will always keep contact with the conductors 28 under all circumstances.

It will be seen that the members 26 are blocks of insulation bolted or otherwise attached to the frame and that the brushes 27 are connected at their rear ends to a metal plate 27a with which the spring 29 engages and that this plate 27a and the brush 27 is mounted upon a pin 30a so that the spring 29 can urge the brushes against the conductor 28 and secure a good contact therewith. The reason for this construction is that where wheels are used for contacting with the conductor as shown in my prior patent before referred to, there is constant chance of the operator, in handling the carriage, getting a shock whereas with this construction, the brushes are entirely insulated from the body of the carriage but are connected by wires to the motor so that the danger of shock is very greatly eliminated.

For the purpose of supporting the rabbit or other lure, I provide a pair of metallic brackets 32. Each bracket 32 extends outward, then downward, then slightly upward at 37 and is provided with two collars 38 into which the butt end of a bamboo pole 37 is disposed. The two poles 39 converge, as shown in Figure 1 and are suitably braced from each other and at their convergent ends support the carrier for the rabbit or other lure. Any suitable supporting means for the rabbit may be used. The brackets 32 are somewhat resilient so that they may yield vertically and thus prevent the lure from being shaken by the vibrations which are communicated to it from the carriage.

I claim 1. A current carrying brush and brush holder therefor including an oscillatable member and curved metallic plates extending from the oscillatable shaft, the extremities of the plates terminating all in the same plane, an arm attached to the oscillatable shaft, and a spring bearing against the arm to thereby urge the shaft in one direction and the metallic plates outward.

SPERO MOCHE.
